" Application filed m 15, 1924. Serial No. 726,152.

This invention relates to carburetors and has particularreference to animproved construction of venturiv so as to insure a swirling action'ofthe gas to bring about 6 a more perfect atomization, a bettercombustion, and a minimum of fuel necessary to operate the en ine.

A further object is to provide a venturi with inclined. or taperingblades or vanes 1 extendingthroughout its length and past the waistlineof the venturi.

This invention is particularly 'designedas an improvement upon theconstruction set forth in my pending application,- Serial No. 704,241,filed April 4, 1924. v I

With theseand other objects in view, the invention consists in certainnovel features of construction and-combinations and arrangements ofparts which will be more fully hereinafter described and pointed out inthe claim. y

Inthe accompanying drawings- Figure 1 is a view partly in section andpartly in elevation illustrating my invention;

Figure 2 is a view in transverse section on the line 2-2 of Figure 1;

Figure 3 is a view in transverse section 'on the line 38 of Figure 1. 1represents. a carburetor of any approved constructiomflitbeing-understood that the carburetor shown is ;for purposes of illusitration only and specifically has nothing whatever to do with, theinvention except to 'which my. improved venturi 2 is located in theoutlet passage 3 of the carburetor.

4 represents a no zzl e having a suitable" needle valve 5wluch'dischargesthe properillustrate a simple form of carburetor in v'Inside of the venturi and fixed to the walls thereof I provide acircular series of inclined blades or vanes 7 which extend from one endto the other of the venturi past the waistline. These blades or vanes 7are widest at their respective ends and narrowest at the waistline oftheventuri so that their inner edges are comparatively in straight linesand preferably these inner edges converge from the lower to the upperend of the venturi, as clearly illustrated in Figure '1 By providingsaid blades or vanes extending throughout the length of the venturi pastthe waistline, a swirling action is insured not only within the venturibut also as the gas leaves the venturi, and by reason of this actionimproved gas isinsured with 'a minimum of fuel consumption.

It isof course to be understood that the invention is not limited to anyparticular number of blades or vanes, but I believe three to bepreferred number although this maybe varied to suit the trade.

Various slight changes and alterations might be made in the general formof the parts described without departing from my invention, and hence Ido not limit myself: to the precise details set forth but considermyself at liberty to make such slight changes and alterations as fairlyfall within the spirit and. scope of the appended claim.

, I-claim: I

A carburetor including a venturi having a restricted portion between itsends, a noz zle located centrally in the venturi and terurinating at therestricted portion of the venturi, and a circular series of inclinedstraight blades projecting inwardly from the wall of the venturi andthroughout the length of the venturi, said blades being angularlydisposed relative to the axis of the venturi and having straight inneredges spaced from the nozzle, the inner edges of 1 the adjacent bladesconverging from the lower to the upper end of the venturi..
